Compilers

The library is intended to be used on multiple platforms and devices. Not every single combination of

compiler/IDE/device/library template have been, or can realistically be, checked. A set of profiles have been created

for the most popular setups.

If you have issues porting the library to your platform then contact me, and I will do my best to resolve any

incompatibilities.

If you have no issues, or have solved it by yourself then please let me know so that I may add information about it to

this page.

I can be contacted here.

___________________________________________________________________________________________________

Visual Studio

Has been compiled under VS2019 and VS2022.

No known issues.

___________________________________________________________________________________________________

GCC

Has been compiled under GNU GCC on Windows & Linux.

No known issues, apart from early versions of GCC that may need to define the macro __STDC_LIMIT_MACROS in the

project properties.

___________________________________________________________________________________________________

Keil uVision

ARM

Define the macro __STDC_LIMIT_MACROS in the project properties.

Compiled with version 5 & 6 ARM compilers.

No known issues.

TI Code Composer

MPS430

Define the macro __STDC_LIMIT_MACROS in the project properties.

In TI projects you have the choice between EABI and COFF file formats.

There is a known issue with the COFF format when creating static libraries that use templates. You may find that the

linker will complain about 'undefined symbols'. The only known workaround is to declare a dummy type in the main

application that uses the template with the same parameter types.

e.g.

If your static library uses etl::vector<MyType, N> then declare a dummy type etl::vector of the same type in the

application.

IAR Embedded Workbench

AVR Compiler

ARM

Define the macro __STDC_LIMIT_MACROS in the project properties.

No known issues.

___________________________________________________________________________________________________

Segger Embedded Studio

ARM

If using STLPort then the macro ETL_STLPORT must be defined in the profile..

___________________________________________________________________________________________________

Greenhills

ARM

No known issues.

___________________________________________________________________________________________________

Zephyr OS

The

ETL

uses 'placement new'.

To enable this from Zephyr you need to add the following to proj.conf:

CONFIG_LIB_CPLUSPLUS=y

CONFIG_NEWLIB_LIBC=y

___________________________________________________________________________________________________

avr-gcc 9.2:

If you are using -std=c++2a you will find the compiler complaining about

redeclaration of C++ built-in type ‘char8_t’ [-fpermissive]

Add this to your etl_profile.h or define it in the project properties.

#define ETL_NO_SMALL_CHAR_SUPPORT 0

You may also want to define

#define ETL_CPP20_SUPPORTED 0

Arduino

Arduino IDE

Visual Studio with Visual Micro extension

The Arduino programming platform is not supplied with an implementation of the STL. The ETL can use of some

features of the STL to compile, and therefore either one must be acquired or the project is compiled with

ETL_NO_STL defined.

A suitable STL implementation may be downloaded from the Arduino library resource; It is called ArduinoSTL.

Add #include <ArduinoSTL.h> to the start of every file that uses the ETL.

Remember to add the directory to the include path.

The alternative option is to compile with ETL_NO_STL defined, if the STL is not used in your project.

Partially tested for Zero, Uno, Yún, Mega, Industrial 101 and Leonardo boards using test_embedded_compile.cpp

Issues

Zero

Arduino101

TinyTile

<algorithm> must be edited to move the template function iter_swap before the declaration of swap_ranges.

The template class variant will not currently compile unless the header file is either renamed or the include path

somehow altered, as the platform also defines a header named variant.h.

Duo

Fails to find ArduinoSTL.h even though it is present.

If ArduinoSTL.h is removed, then fails with printf has not been declared.

General

It may be necessary to add the following lines to the beginning of the file.

#undef min

#undef max
